Missed the equation meaning.

Problems arise frequently when you are right-brained and tend to see math in visual form.

Yeah....13 in base 13 means one 13 and 3 ones.

I forgot to see it in a columnar format as opposed to a number of a whole.

In base 10, numbers are made up of 1's, 10's, 100's, 1000's and so on, because they are 10¹, 10², 10³ and so on.Base 13 is similar, but it's made up of 13°'s, 13¹'s, 13²'s and so on.

That means that 13 in base 13 is 1*13+3 = 16, half of which is 8.

But is not 13 in base 13 = 1?

That being the case, how can the answer be Half of 13 in base 13 is 8?

In base x, 13 would be x + 3 (we have base 10, so 13 is 10 + 3), which means that your thing would be (x + 3)/2 = 8.Shifting the 2 gives x + 3 = 16, so the base is 13.]]>http://www.mathisfunforum.com/profile.php?id=6412005-11-08T16:44:31Zhttp://www.mathisfunforum.com/viewtopic.php?pid=17717#p17717THe puzzle is this:

When is half of 13 equal 8? (Hint: different number system)

I have tried this one with different bases (Base 3 Base 5 etc) and in Hex and Octal...I am either missig something or I am way off track.
